Kate Middleton and Prince William took home something very special when they left St. Mary's hospital on Tuesday, July 23 -- and we're not just talking about their newborn son, Prince George Alexander Louis. Prior to their departure, the Duke and Duchess of Cambridge were presented with a celebratory scroll commemorating the royal baby's birth, a scroll almost identical to the one given to Prince Charles and Princess Diana upon William's birth 31 years ago.

The scroll -- inscribed by hand and enclosed in an embossed leather case -- expresses the hospital staff's "pride and delight" that Prince George was born in the Lindo Wing at St. Mary's Hospital (the very same wing where his father was born on June 22, 1982). It reads:

"The Chairman, Directors and Staff of Imperial College Healthcare NHS Trust are deeply honoured and would like to express their pride and delight that The Heir to the Throne of Great Britain and Northern Ireland and the other Realms and Territories was born at St. Mary's Hospital Paddington on 22 July 2013. We send our loyal and affectionate congratulations and greetings and we wish the baby Prince and his parents Their Royal Highnesses the Duke and Duchess of Cambridge a long and happy life together in peace, good health and freedom."

In a statement about the gift and the happy occasion it represents, the chairman of Imperial College Healthcare NHS Trust, Sir Richard Sykes, said: "Like people up and down the country, I was delighted to hear the news that the Duchess of Cambridge has had her baby boy. On behalf of everyone at the Trust I would like to congratulate Their Royal Highnesses on the new arrival."

"It will always be a source of great pride for the Trust and everyone who works here that the baby, like his father, was born in the Lindo Wing at St. Mary's, and we would like to wish him the very best of luck for the future," Sykes continued. He went on to thank "the team at the Lindo Wing and all those members of the Trust staff, and volunteers who have worked tirelessly to ensure that the Duke and Duchess received the best possible care."

Per a press release about the celebratory scroll, "The Duke and Duchess have invited well-wishers who would like to give their own gift to consider instead making a donation either to a local children’s charity or to the charity which raises funds for the hospital trust where the Duke and Duchess's baby was born."
